它通过计算当前收盘价与一定周期前的收盘价的差值与这段时间内价格波动的范围的比值，来判断目前的股价走势是趋势还是盘整。
|

市场波动指数CMI的计算公式：
|

CMI=(Abs(Close-ref(close,(n-1)))*100/(HHV(high,n)-LLV(low,n))
|

其中，Abs是绝对值。
|

n是周期数，例如３０。
|
||
市场波动指数CMI的使用方法：
|
||
这个指标的重要用途是来区分目前的股价走势类型：盘整，趋势。当CMI指标小于２０时，市场走势是盘整；当CMI指标大于２０时，市场在趋势期。
|
||
CMI指标还可以用于预测股价走势类型的转变。因为物极必反，当CMI长期处于０附近，此时，股价走势很可能从盘整转为趋势；当CMI长期处于１００附近，此时，股价趋势很可能变弱，形成盘整。
